Detailed Description

template<class T>
class LinkedList< T >::iterator

Defines an iterator of a list of type LinkedList.

The iterator is used to iterate over the elements of a list. The iterator at each moment is pointing to an element in the list. Example of usage:

        
LinkedList<int> list;
LinkedList<int>::iterator iter;
int val;
for (iter=list.begin(); iter!=list.end(); iter++) { // iterating over the elements
        val = (int)(*iter); // extracting the value
        .
        .
        .
}

Constructor & Destructor Documentation

template<class T> LinkedList< T >::iterator::iterator (    )  [inline]

Default constructor. Initializes the iterator to point to nothing.

template<class T> LinkedList< T >::iterator::iterator (  const iterator &    iter )  [inline]

Copy constructor. Initializes the iterator to point at the same element as iter Parameters: iter  A reference to a list iterator to copy

Member Function Documentation

template<class T> T& LinkedList< T >::iterator::operator * (    )  [inline]

Returns the value of the element pointed to by this iterator. Returns: A reference of the value pointed by the iterator

template<class T> bool LinkedList< T >::iterator::operator!= (  const iterator &    iter )  [inline]

Compares the 2 iterators (by the elements they're pointing to. Parameters: iter  The iterator to compare to Return values: true  The 2 iterators point to different elements false  The 2 iterators point to the same element

template<class T> iterator LinkedList< T >::iterator::operator+ (  int    inc )  [inline]

Updates the iterator to more forward inc elements in the list (postfix operator). Parameters: inc  The number of steps to move forward in the list Returns: A copy of the iterator

template<class T> iterator LinkedList< T >::iterator::operator++ (  int    )  [inline]

Updates the iterator to point on the next list element (postfix operator). Returns: A copy of the iterator

template<class T> iterator& LinkedList< T >::iterator::operator++ (    )  [inline]

Updates the iterator to point on the next list element (prefix operator). Returns: A reference of the current iterator

template<class T> iterator LinkedList< T >::iterator::operator- (  int    inc )  [inline]

Updates the iterator to more backwards inc elements in the list (postfix operator). Parameters: inc  The number of steps to move backwards in the list Returns: A copy of the iterator

template<class T> iterator LinkedList< T >::iterator::operator-- (  int    )  [inline]

Updates the iterator to point on the previous list element (postfix operator). Returns: A copy of the iterator

template<class T> iterator& LinkedList< T >::iterator::operator-- (    )  [inline]

Updates the iterator to point on the previous list element (prefix operator). Returns: A reference of the current iterator

template<class T> iterator& LinkedList< T >::iterator::operator= (  const iterator &    iter )  [inline]

Updates the current iterator to point to the same element pointed by the given iterator. Parameters: iter  The iterator to copy Returns: A reference of the current iterator

template<class T> bool LinkedList< T >::iterator::operator== (  const iterator &    iter )  [inline]

Compares the 2 iterators (by the elements they're pointing to. Parameters: iter  The iterator to compare to Return values: true  The 2 iterators point to the same element false  The 2 iterators point to different elements
